Description

Clamping washer for supporting stand for structures, and supporting stand for structures using the same {Clamping washer for supporting stand, and supporting stand using the same}

The present invention relates to a clamping fixture for a structural support stand for supporting pipes or structures. In particular, a clamping washer for a structural support stand that can adjust the height of the structural support stand and at the same time be firmly fixed with a high rigidity structure, and the same. This relates to the structural support beam used.

Typically, a support bracket is installed on the ceiling of a building to support pipes, cable trays, and other various devices or facilities. These support beams are installed horizontally at regular intervals on the ceiling of a building, and pipes, cable trays, and other structures are fixed on them. As members of the structural support stand, section steels of various shapes, such as "L" shape, "ㄷ" shape, "I" shape, and "H" shape, are used. These section steels are cut to size in a vertical or horizontal direction. It is made up of channels arranged in different directions, that is, vertical channels or horizontal channels, and are welded together to become a support stand for the structure. However, when the channels are welded together, there is a problem of inconvenience due to on-site welding by workers and increased work time, which increases costs, so prefabricated support stands are often used. The prefabricated support stand is structured to be fastened with bolts and nuts through brackets between the vertical channel and the horizontal channel. In the case of the above-mentioned prefabricated support stand, the height or spacing can be adjusted to some extent by the long bolt holes provided in the channel, but in this case, the bolts in the long hole bolt holes do not provide shear resistance and are fixed only by surface contact, so the height of the support stand is Not only is it difficult to set up, but especially when a structure with a high load is stationary, a problem has been pointed out that it is installed tilted to one side rather than being horizontal. Therefore, there is a demand for a clamping fixture for a structural support stand that can stably support pipes or high-load structures while allowing height adjustment according to installation conditions. An example of the prior art regarding the clamping fixture for the support stand is disclosed in Korea Registered Utility Model No. 10-2021-0002780 (name: Support for adjusting the height of pipes) (hereinafter referred to as 'prior art 1').

In the case of prior art 1, a height adjustment piece provided with a sawtooth-shaped adjustment groove is disclosed. The height adjustment piece is formed on one side, and is attached to each side of the bracket and the vertical channel that face and contact each other, and the vertical channel is adjusted by varying the engaging positions of the height adjustment piece of the vertical channel and the height adjustment piece of the bracket. The position can be adjusted up and down. However, the height adjustment piece is fixed with welding or rivets because a slip problem occurs between the bracket and the vertical channel. In this case, the versatility of the bracket and the vertical channel is reduced and their use is limited, and a separate There is a problem that welding or riveting work is inconvenient and the unit price increases. Therefore, a method is needed to expand the versatility of brackets and vertical channels and to enable them to be assembled more firmly without additional work.

Meanwhile, another example of the prior art regarding the clamping fixture for the support stand is disclosed in Korean Patent Publication No. 10-2010-0061423 (name: Piping support stand with height adjustment device) (hereinafter referred to as ‘prior art 2’). .

In the case of prior art 2, a height adjuster whose height can be adjusted up and down through the fastening hole of the bracket is disclosed. The height adjuster has an overall "T"-shaped cross-sectional shape, the central part of which is accommodated in the fastening hole of the bracket, and the peripheral part is fixed to the outer surface of the bracket, and the side of the central part has teeth formed in the fastening hole of the bracket. A sawtooth-shaped height-adjusting protrusion is provided so that it can fit into the height-adjusting groove of the shape. According to this configuration, the height of the vertical channel can be adjusted up and down by varying the height adjustment protrusion that fits into the height adjustment groove. However, because the peripheral portion of the bracket is hung on the outer surface of the bracket, the central portion of the bracket cannot be closely attached to the vertical channel, and as a result, the fastening force of the bolt is pressed only to the peripheral portion of the height adjuster, which limits the firm fastening of the high-rigidity structure. there is. In order to stably and firmly support structures such as pipes that vibrate up and down and left and right due to earthquakes or vibrations, especially fluid flow, a clamping fixture for the support stand with a more robust and high-rigidity structure is needed.

This is a cross-sectional view showing the vertical channel being pressed and fixed integrally with the bracket.

First, terms used to describe a clamping washer and a structural support stand using the clamping washer as a preferred embodiment according to the present invention will be explained. In the field of the present invention, "L" shape, "ㄷ" shape, "I" shape, "H" shape, "C" shape and other various shapes of section steel are cut into appropriate sizes at the installation site as structural members or non-structural members. It is being assembled on a support stand. In particular, the “C” shaped profile is a member that is bent by a roll forming machine and has a slot formed in the longitudinal direction, and is referred to as a channel in the field of the present invention. Hereinafter, section steels assembled on a support stand are collectively referred to as ‘channels.’ The channels are located at regular intervals on the ceiling, floor, or wall of a building. In order to fix them, two or more channels are connected to each other to form a structure, and various other devices such as pipes, cable trays, and other devices, equipment, or facilities are installed on them. The structure is fixed. These structures generally require horizontal channels arranged in a horizontal direction for safety, and also require horizontal channels arranged perpendicular to the ground to fix and support them. Horizontal channels and vertical channels are generally arranged at right angles, but they do not necessarily have to be at right angles. However, for convenience of explanation and understanding, one of the channels placed across each other is called a 'horizontal channel' and the other is a 'vertical channel'. This is explained as an example using terminology. In general, width, length, or direction are relative concepts and can vary depending on perspective. For convenience of explanation and understanding, 'length direction', 'width direction', and 'fastening direction' are used in relation to direction. In the case of the support stand according to the present invention, a configuration in which clamping washers are combined and assembled with brackets in the longitudinal direction of the channel will be described. Accordingly, a channel is a type of section steel and will be described and shown as having a shape that is longer than the width. Accordingly, the 'longitudinal direction' refers to the longitudinal direction of the channel based on the channel that is longer than the width, or when assembled and oriented in the channel. As such, the 'longitudinal direction' of the bracket refers to the same direction as the longitudinal direction of the channel, and when assembled and oriented with a bracket, the 'longitudinal direction' of the clamping washer refers to the same direction as the longitudinal direction of the channel. In addition, the 'width direction' refers to the width direction of the channel based on the channel being longer than the width, or when assembled and oriented in the channel, and the 'width direction' of the bracket refers to the same direction as the width direction of the channel, when assembled with the bracket. When oriented, the 'width direction' of the clamping washer refers to the same direction as the width direction of the channel. And, as in an example of fastening with fasteners such as bolts and nuts, the “fastening direction” is used as the direction in which clamping washers, brackets, and/or channels are fastened and pressed together.
